Specification of Letters Patent. Patented Feb. 18, 1919. I

Application filed May 29, 1913, Serial No. 77Q,558. Renewed July 9, 1918. 'Serial No. 244,122

To all whom it may concern: Be it known that I, EDWARD H. SGHRIEFER,

a'citizen of the United States, and a resident of Cincinnati, Hamilton county, Ohio, have invented a new and useful Fire-Resisting Cabinet, of which the following is .zuspecification. N s s My invention relates to improvements in fire resisting'cabinets'and has for its principal objectthe provision of a device of simple and economical construction possess 'ing rigidity and strength when assembled,

and features enabling it to withstand very high temperatures Without resultant loss to its contents or serious damage to itself.

I am aware of various previous patents which have been granted on devices of this nature, but my structure has many advantages over the previous forms as will be" seen from the specification and drawings herewith, in whichv 1 Figure 1 is a reduced view of the blank used in making the member illustrated in Fig.2 is a-view of the blank shown in Fig. 1 after it"has been notched at the corners, the dotted lines showing wherethe bends are to be made. Fig: 3 is'a perspective the main frame.

. outer back wall.

Fig. 5 is a vertical section from the front tothe back of ,the structure. Fig; 6 is a horizontal section.

Fig. 7 is a vertical section fromside to side of the structure on the line 33 of Fig. 5.

Fig. '8 is a diagrammatic'view of the in ner back member showing the outline of the same in vertical cross section.

Fig. 9 is a diagrammatic view of the inner backmember, showing the outline of the same in horizontal cross sectlon.

Fig. 10 is a diagrammatic v1ew of the inner top member; showing the, outline of the same in-v'ertical cross section from the front to the back-of the structure.

Fig. 11 is a diagrammatic view of the inner top member, showing the outline'of the of one element of iig. 4 is a perspective of a portion of the same in vertical cross section from side to sideof the structure.

Fig. 12 is a diagrammatic view of the inner. bottom member, showing the outline of the same in vertical cross section from the front to the back of the structure.

Fig. 13'is a diagrammatic view of the inner bottom member, showing the outline of the same in vertical cross section from '23, as shownin Fig. 2, to form the structure shown in Fig. 3, the parts 24, and 26, constituting respectively the outer side or end wall, the outer top wall and the outer bottom wall of the cabinet. Rectangular flanges 27, 28 and 29 are formed by the bends 'on the dotted lines, and secondary" flanges 30, 31 and 32 at right angles to the flanges 27, 28 and 29 areformed by additional bendings.

It is obvious thattwo structures as shown in Fig. 3 can, be placed together with the flanges 33 in juxtaposition, and the said flanges can then be welded together to form practically. a hollow cubewith closed top, bottom and sides afid'fbpen back and" front with inwardly extendingflanges 30, 31

and 32. This'structure' can be made of one sheet of metal if preferred, but as shown herein is made of two sections,;but after they are welded, it is practicallyintegral and possesses great stre'ngth'and rigidity.

The outer back wall, as shown in Fig. 4, is formed of one piece of sheet metal and comprises the rear plate 34; withperipheral 'U shaped flanges 35. After this member is formed it can be inserted through the opening 36 in the front of the elemental frame just described and'moved rearwardly until the flanges 30 on the back of the frame enter U P ng s 35 o the outer back wall. These three thicknesses of metal can then be locked together in any suitable manner, but preferably by using a punch tocut loose in the three Sheets, two. sides and one the line of engagement of the flanges and the U shaped flanges on the outer back wall.

In this manner we obtain a very rigid and secure locking together of the elemental frame and the outer back Wall and obviate the danger of buckling or warping if the back of the cabinet should be subjected to very intense heat.

The inner back wall as shown in Figs. 5 and 6, comprises a wall member 38 with compound flanges 39, 40 and 41 on its upper and lower ends and the compound flanges 42, 43,

and 44 on its sides. A light sheet of suitable insulating material 45 and a'heavier sheet of the same 46, are placed upon one side of this member and blocks 47 of similar material are located opposite the joints formed by the flanges30 on the outer frame and the flanges 35 on the outer back member 34.

The flanges 41 and 44 setting in behind the projections 37 and 37 serve to hold this inner back wall securely in "position. Heavy sheets of insulating material 49 and 50 are shown respectively at the top and bottom of the structure and a dead air space 48 is provided between the inner and outer walls of the structure. I

The inner top wall 51 consists of a sheet of metal provided on its sides with flanges 52, which engage with the insulating material 24 on the outer side walls 24. A flange 53, and compound flanges 54 are providled respectively at the rear and front en s.

The inner bottom Wall 55 is similar in construction to the inner top wall 51 and is held in pace in like fashion, the side flanges 56 engaging with the insulating material 24 on the outer side Walls 24 and the front and rear end flanges being identical with those on the member 51. 'The inner side walls 57 consist of metal sheets provided with top and bottom flanges 58 adapted to engage with the insulating material 24 on the outer side walls 24, double flanges 59 at the rear ends and compound flanges' 60 at the front ends. These inner side walls are placed in the structure after the other-walls are assembled and are held in position by the projections 64on the inner back member. v v

Shelves are used-in constructions of this nature on which'books, papers, rollers, files, drawers, .etc., etc.,,ar e supported and these shelves are usually secured to the inner side walls 57. To prevent this heavy weight from buckling or breaking down these inner walls, channel irons 61 and 62 are placed respectively beneath and above the line of the said walls between the inner and outer walls of the cabinet, and casters 63 are also shown directly under this line of greatest resistance. The upper channel irons 62 are of particular service during shipment of the cabinets, as, when boxed or crated, the said cabinets are frequently turned upside down and if a heavy equipment of shelves, files, etc., were installed in the interior, there would exist a liability of the inner top wall of the structure being injured. I

The doors of the cabinet as shownhave interlocking projections 65 at their abutting joints, and tongues 66 to coiiperate with the recesses 67 in the inner wall members and thereby make an efiicient heat resistin joint. The doors are lined with a sheet 0 insulating material 68 and have a heavier insulating material 69 on their inner front sides. Hinges 70 are secured to the doors in a suitable manner through the reinforcement 71 inside the outer sheet 72 of the door, and are suitably secured to the main structure through the reinforcement 73 inside the outer sheet of the said main structure.

Surroundin the cabinet on three sides is the base molding 74, secured by the clamps 75, and a crown plate 76 provided with a coping 77 and a straight flange 78 at the rear, secured to the cabinet by the screws 79, and in the front by a resilient member 80. A sheet of insulating material 81 is placed between the top of the elementary structure and the said crown plate 76.
